Rockies 4, Diamondbacks 1

DENVER -- Carlos Gonzalez drove in two runs with a homer and a triple Wednesday, while Jorge De La Rosa won his fourth straight start as the Colorado Rockies beat the Arizona Diamondback 4-1 in the rubber game of their series.

With closer Rafael Betancourt sidelined with tightness in his right groin, Rex Brothers worked the ninth and earned his second career save, the other coming Aug. 23, 2011, here against the Houston Astros. Brothers made his 19th consecutive scoreless appearance and lowered his ERA to 0.42.

The victory was the fifth in the past six games for the Rockies, who won three of their final four games against San Francisco and completed a 5-2 homestand against the Giants and Diamondbacks.

De La Rosa threw 103 pitches, the most by a Rockies starter this season, in 5 1/3 innings and allowed six hits and one run. The Rockies staked him to an early four-run lead, scoring twice in both the first and third innings against Trevor Cahill.

Gonzalez, who went 2-for-4, had early visions of hitting for the cycle, which he did last year. He was a triple shy of the cycle -- he didn't get it -- May 14 at Chicago where he finished 5-for-5.

After hitting a home run on his first at-bat, Gonzalez tripled on his second, the hit in the third inning scoring DJ LeMahieu, who had reached base on an infield single. Gonzalez scored on Cahill's wild pitch to give the Rockies a 4-0 lead.

Gonzalez hit his 11th homer with two out in the first, and Dexter Fowler and Nolan Arenado followed with doubles to put the Rockies ahead 2-0.

De La Rosa gave up a run with two out in the fourth when Wil Nieves doubled on a nine-pitch at-bat. The hit scored Cody Ross, who had singled and moved to second on a ground out.

De La Rosa allowed consecutive singles in the fifth to AJ Pollock and Didi Gregorius, but avoided trouble by getting Paul Goldschmidt to ground into a double play. De La Rosa gave up a leadoff single to Ross in the sixth and struck out Gerardo Parra before giving way to Edgmer Escalona, who pitched 1 2/3 scoreless innings. Matt Belisle provided a one-inning bridge to Brothers.

The Rockies have won seven of 10 games started by De La Rosa, who is 6-3 with a 3.40 ERA. It will be two years on Friday that De La Rosa tore the ulnar collateral ligament in his left elbow in a start here against Arizona. His recovery from Tommy John surgery was lengthy, but based on his performance this year, is finally behind him.

NOTES: Betancourt, who left Tuesday night's game with right groin tightness, received an anti-inflammatory shot and hopes to be ready to pitch Friday. Betancourt has inflammation around scar tissue from a 2009 injury. ... Rockies shortstop Troy Tulowitzki was given a planned day off, which because Colorado doesn't play Thursday, will give him two days. He had started 13 straight games. ... With Tulowitzki and C Wilin Rosario resting and Michael Cuddyer on the disabled list, manager Walt Weiss had Fowler, who typically bats first or second, batting cleanup. It was his first career start hitting fourth. The only other time Fowler hit fourth was as a pinch hitter this season on April 10 at San Francisco when he grounded out in the eighth inning in a 10-0 loss. ... The umpires used video replay to uphold the call by first base umpire Doug Eddings that the ball Fowler hit down the right field line in the sixth was foul. ... Rockies pitcher Jeff Francis (left groin strain) felt fine after a 25-pitch bullpen session Tuesday. He will travel with the team to San Francisco where he will long toss Friday and throw another bullpen session Saturday. ... Diamondbacks manager Kirk Gibson said outfielder Adam Eaton (strained left elbow), who has been on the disabled list since the start of the season, was scheduled to see team physician Michael Lee on Wednesday in Phoenix. He has been on a rehab assignment with Triple-A Reno and experienced discomfort in the elbow making his first throw during a game Monday in Round Rock, Texas. ... Cahill had allowed three homers in 58 innings before yielding a homer to Gonzalez in the first inning.
